vice travelling past said supply holders at a higherelevation than thesupply holders themselves, and

the provision of means for 'transferring the bohbins from said feedingdevice down-to said 35 ply holders, and means for releasing the bobhinsso as to allow them to drop or sliponto the supply holders. Y

The bobbin feeding device may consist of a carriage having trough-shapedchutes with means 26 for automatically releasing a bobbin in front of Yevery supply holder-so' as to allowit to'drop or slip down on to thelatter. As an alternative, the bobbin eedingdevice may consist of atravelling endless conveyor formed by a chain, belt, or the 5 like, toconvey the bobbins in horizontal position to the various unwindingstations, where they are brought by means of a separate device into theposition of readiness for'them to drop or slip down freely on to theempty supply holders.. The travelling conveyor may be iitted withtrough-shaped holders for the separate individual bobbins to bearrangedon theconveyor in slanti ing position so that the bobbins liefrom the very rst in readiness forfdropping. In these rests the bobbinsare retained by suitable means until they have arrived at the individualunwinding Stations whereupon the means retaining the bobbin arereleased, thus allowing the bobbins to' drop or slide down onto thesupply holders by means of stationary chutes.

In thesefigures, I is a magazine for the full bobbins, which travels alongpastthe .un- Awinding stations. 3 are thefull bobbins which are 1 rurged toward a star-shaped single feed device 4 j by an inclined bottom3 of the magazine. The magazine I is moved past the unwinding stations Yby means of a screw spindle 5 driven by. suitable means. not shown, andengaged by an internally.A threaded bush 6 'on the magazine. In place'ofthe screw spindle i there can, of course, be used 'any other suitabletransmission means for imparting motion to the magazine.

February 17, 1931, now Patent No. 2,010,465, Aug. 6, 1935, which in thiscase also are free to rotate about an axis Il and are held in theirvarious Y working position, the empty bobbin being removed Y positionsby a'retaining device. As in the above patent, there -is a deflector I5on the travelling magazine I, which takes care of the advancement of thestar-shaped bobbin holder I2 to its next from its holder at the sametime by a stripper I6. The form of machine described above provides forthe transfer of the unwinding bobbins to their holders simply by theweight of the bobbins themselves, without the use of any positivelyacting shifter. Y y

Figures 3 to 9 show a different embodiment in which the full supplybobbins are taken from a preliminary magazine mounted at the end of themachine by a chain or the like for conveying them to the Vseveralunwinding stations. Here however the bobbins are not positively pushedupon the holders I2, but fall upon them by their own weight, as in thefirst embodiment. For this purpose, as soon as the bobbins 2 arrive attheir bobbin stations, they are engaged at their pointed ends by acommon rail or frame element 68 and raised to the preparatory positionshown in Fig. 4,

bobbin holders I2. Here' the deilector I6c is mounted, not upon thebobbin conveyor Ila, but upon a separate ccmveyor 15.

Figs. 'I-9 show an auxiliary device which has the purpose of preventinga charging and discharging of bobbin holders in which .there arerremnants of yarn not yet unwound, as occurs when the yarnbreaks, theobject being to permit this remnant to be completely unwound along withthe others when the yarns of the next set of bobbins have beenknotted-to those on the winding packages. A separate stationary feeleris provided at each winding station. From Figs. 7 and 8 it can be seenthat beside every bobbin holder I2 on the same bearingrod I I isfastened a holder III. On the latter is rotatably mounted an angularlybent feeler III. The upper end of this i'eeler III'is made'in the formof a hook at II2 (Eg. 9) while the lower end I I2 may be straight. Sincethe upper hook-shaped end II2, whenever there is no more yarn on thebobbin 2, rests against the foot of the bobbin, it is held intheposltionshownin fulllinesinthethreeupper Only when the bobbin 2 hascompletely run out does the Ieeler swim into the position shown in thelowermost lmwinding station of Fig. 9. Now when the traveling deilectorI6c comes to an unwinding station in which there is a remnant of yarn onthe bobbin, because of breakage of theyarn, an angleshaped lug I I4 onthe deector Isc strikes against the end of feeler I I 3' presentedtoward it. There- `by the end III of the feeler is carried alongtothe/position shwn in dotted lines in the third unwinding station fromthe top of Fig. 9. By this movement of the feeler end II3 the deflectorI5c is moved into the dotted 'line position at this station and therebyan advancement'of the .bobbin lholder is prevented. The delivery of anew bobl bin 2 (Fig. 19) is not prevented in this form 'of Figures 1o to13 show the third form of the invention.

Here the full bobbins 2 are brought to the unwinding stations by anendless chain I1d in position ready to dropuoif, but the bobbins fallfrom a stationary magazine arranged at the end of the machine upon theconveyor directly in the position ready to slide 01T, as is shown inFigs. 10 and 13. 'I'his is done by making the bobbin seats on theconveyor in the form of inclined troughs 16, which ares'ecured to theconveyor chain Ild by means of supports 11 and 18 of different heights.At the lower ends of troughs 16 are provided spring aps 19, which holdthe bobbins 2 in position as they travel to the unwinding stations.After all the bobbins have arrived at their bobbin stations, the flaps19 are mov'ed by a common control device from the position shown in Fig.10 to that shown in Fig. 11, whereby the bobbins 2 immediately fall uponthe corresponding peg of the bobbin holder, sliding down upon thestation ary Ychute 14 on the way. The operation of the aps 19 can beaccomplished 4by means Atif-a through-going shaft 80 having fastenedthereon individual levers 8 I or corresponding throughgoing rails, whichhave noses to engage levers or projections 82 on the flaps and ltherebyrelease the ilaps from their blocking position, as shown in Fig 11. Theactuation and control of the shafts can take place by hand lever 83, asin the previous embodiments.

In Fig. 10 the bobbin stands prepared to drop,-

in Fig; 11 it has dropped down upon the bobbin holder, in Fig. 12 theflap 19 has returned to its blocking position, and in Fig.A 13 thebobbin 2 has been moved' by the deilector I5d into operative position,the unwound empty bobbin tube having been stripped oi at the same time;

Figs. v14 and 15 show a form ofthe invention which uses in part, the'/idea of, thefirst' embodiment (Figs. 1 and 2) and in part that of thethird embodiment (Figs. 10 to 13). In this case the travelling magazineIf lets the full bobbins 2 fall directly upon stationary rests 86, whichbring the bobbins to the inclined positions, as in the case of Figs. 10to 13. 0n these rests the bobbins are retained by a comm'n vrail 85. Therail 85 controlling a plurality of-bobbins simultaneously is broughtfrom the blocking position to the position indicated by dotted lines inFig. 14, either by a hand lever 89 'or automatically, whereupon thebobbins slide down onto the holder I 2 by their own weight. Stationaryintermediate troughs Tlf are also provided to guide the bobbins 2accurately onto the bobbin holders I2 as they slide down.

In the embodiments illustrated in Figs. 16-18, the peg SII is tiltableand the bobbin glides down upon it. The bobbin peg is pivoted to theupper end of a rod 3II vertically slidable inbearings 223e. Forimparting a swinging motion tothe peg, it is provided with an arm 3I2.This motion of the peg occurs upon the downward pull of rod 3l I causedby the action of deilector I5s upon its arm 3I3. As the peg supportingrod moves downward from the dotted line position to the full lineposition in Fig. 16, the peg is tilted by the ann 3I2 striking againstan abutment 3| I. the peg 3I0 is tipped to the inclined position shownin full lines in Fig. 16. At the moment the peg orholder 3I0 has reachedthis inclined position, chute 3I5 of the travelling magazine 3I6 arrivesopposite an opening in the stationary angle iron 3II,'so that the bobbinAslips down through this opening over the inclined trough 3'I3 and uponthe bobbin peg 3III. After the deector I5s mounted on the magazine 3I6vhas moved on and left the arm 3| 3 of rod 3| I, the latter rod ilies upunder the action of spring 3I9 to the position shown in4 dotted lines.The dotted lines show how arm 3I2 has struck against the lower edge ofangle iron 320 in its upward movement and has thereby swung the bobbinholder 3 I 0 into the vertical working position. The stripping oi'of theempty bobbin tube is accomplished simply by the downward movement of r3II impelled by detlector lis.' 4

In Fig. 18 there is usedin place of the travelling magazine an endlessconveyor band'32l upon` which the bobbins lie on rests 322 in theinclined I position required for their downward sliding. In

this position the bobbins are held during the travel ofthe conveyor bandby a spring -ilap 323.

Just at the instant when the bobbin holder 3III has come to receivingposition by the operation of pedal 229d on rod 22Id,.the arm 324fastened on rod 22Id opens flap 323 of the' bobbin rest 322, so that theb'obbin 2 can-slide down freely onto the waiting bobbin peg. The othercharging motions are the same in this embodiment shown in Fig. 18 asthose shown in Figs. 16 -and 17.
